hanger being then provided with a separate angle.

While obviously I may make the plate 12 common to all the hangers, for example a circular angle plate surrounding the chute, I prefer however to keep the plate supports of the individual hangers individually independent, both because the structure is then better adapted to very easily accommodate individually different conditions at different floors or at the same floor and also because it is less expensive to install.

The angles 17 are preferably straight and of any suitable length and are fastened to the floor structure with one flange 18 horizontal and the other flange l2 directed vertically upwardly.

I secure the flange to the floor structure in any suitable way as by bolts 19, and then extend the hanger up over the vertical flange and thence downward to the horizontal outwardly extending flange l8, fastening it to place against the flatflange by the bolt 15 and rectangular washer 16, as clearly indicated in the figures.

The number of hangers required at each floor.

will of course vary with the individual chute. I

prefer to use four, as shown in Figures 1 and 2,

tionsand modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all 'or part of the benefits of myinvention without copying the structure shown, and I, therefore, claim all such in so far as they fall Within the reasonable spirit and scope of' my invention.

Having thus described my invention,'what I claim as new and desire to secure by Letters Patent is-:- r

' 1. In a chute of the character indicated, an aluminum chute section passing through a floor opening, a flap of aluminum having one end Welded to the outside of the chute, a member carried by the floor and having an upwardly directed edge, said'flap extending upwardly from its said N one end over the edge and thence downwardly and means fastening the outer end of the flap after it has extended downwardly from the upper edge'of the flange.

2. In a. chute of the character indicated, floor structure passing the chute, a metal angle supported on the structure and having a vertical flange near the chute and a horizontal flange extending therefrom outwardly with respect to the chute in combination with a metal flap having a high intermediate portion supported on the upwardly directed edge of the vertical flange and low inner and outer ends fastened respectively to the outside of the chute and to the top of the horizontal flange.

3. In a chute of the character indicated, a floor structure passing the chute, a metal angle supported on the structure and having a vertical flange near the chute and a horizontal flange extending therefrom outwardly with respect to the chute in combination with a metal flap,

having a high intermediate portion supported on the. upwardly directed edge of the vertical flange and low inner and outer ends respectively welded to the outside of the chute and fastened to the top of the horizontal flange.

4. In a chute of the character indicated, floor structure passing the chute, a metal angle supported on the structure and having a vertical flange near the chute and a horizontal flange extending therefrom outwardly with respect to the chute in combination with a metal flap, having a high intermediate portion supported on the upwardly directed edge of the vertical flange and lower inner and outer ends respectively welded to the outside of the chute and fastened to the top of the horizontal flange with the outer end clamped flat down to. the top of the horizontal flange. I

5. In a chute of the character indicated, floor structure passing the chute, a plurality of straight metal angles supported on the structure" at intervals around the chute and each having a vertical flange near the chute and a horizontal flange extending therefrom outwardly with respect to the chute in combination with a metal flap at each angle having a high: intermediate portion supported on the upwardly directed edge of the vertical flange and low inner and outer ends fastened respectively to the outside of the chute and to the top of the horizontal flange.

6. a chute of the character indicated, a chute section passing through a floor opening, a plurality of angles having vertical and horizontal' flanges directed respectively upwardly and outwardly and metal 'flaps fastened tothe outside of the chute at-the respective angles and extending up from the point of fastening over the vertical flanges and thence downwardly fastening to the horizontal flanges.
